2 Chronicles 32:1-3

1After Hezekiah’s faithful deeds, King Sennacherib of Assyria came and entered Judah. He laid siege to the fortified cities and intended to break into them.

2Hezekiah saw that Sennacherib had come and that he planned war on Jerusalem,

3so he consulted with his officials and his warriors about stopping up the water of the springs that were outside the city, and they helped him.
